  "description": "Normal operating procedures for the Beechcraft Bonanza A36 with Continental IO-550 fuel-injected engine, constant-speed propeller, and retractable tricycle gear. Covers preflight walk-around through shutdown and securing. All airspeeds, power settings, fuel quantities, manifold pressure values, and performance data must be taken from the specific aircraft POH. The IO-550 is fuel-injected — there is no carburetor heat. The fuel selector has three positions (LEFT, RIGHT, OFF); confirm the selected tank before every phase. The A36 has an emergency landing-gear extension handle; familiarise yourself with its location before flight. Not a substitute for qualified instruction or type-specific checkout.",
